How can I make a power rail inactive when it's next to an active one?

I'm building a Minecart track. In order for it to work correctly, I need the minecart to stop in the middle of the track, and the best way to do that is to use a power rail that is not receiving a redstone signal.

The problem is that the inactive power rail needs to be placed close to a powered rail, and powered rails are made active if they are within 8(?) blocks of a redstone signal.

I want the powered rail on the stone block to be turned off.

Is there any way to do this?


The easiest way to do this is to simply place a powered rail between two normal rails and not connect it to a power source. Normal rails do not "conduct" redstone power, so the setup in this screenshot results in the powered rail on the stone block being inactive.

Another option for tracks at least 10 blocks long is to place 1 powered rail connected to an active redstone source and 9 powered rails not directly connected to a redstone source. The last powered rail will then be inactive.
